While true that it is still na, you have a large advantage over a stock car due to like you said, cams. That is effectively the brain of your engine and you may unlike a stock car actually benefit from the bigger tb. I am not sure because I am by far not an expert on the transversly mounted 4 banger but I grew up tearing apart and rebuilding hot rods. I know when you go from a restrictive stock cam on an average mild 300+ horse V8 to a decent lift and duration cam, your power is amazingly improved just because the car no longer falls on its face at about 5500 rpms due to the emmisions freindly cam, it will pull hard as hell toward the 7k mark or whatever depending on the specs. Thing is, when you are revving that high with that much valve lift, you are sucking a lot more air therefore the bigger mani and tb will help out with the new bottle neck you created by the cam. On a more modded car such as yours, the tb will probably have a much more favorable effect than a bone stock bolt on car.
